文 献：PI-103 is a potent and selective PI3K inhibitor with low IC50 values against PI3K isoforms p110α (2 nM), p110β (3 nM), p110δ (3 nM), and p110γ (15 nM). PI-103 at 0.5 µM also inhibited TORC1 by 84% and demonstrated an IC50 of 14 nM against DNA-PK. PI-103 potently inhibited proliferation and invasion of a wide variety of human cancer cells in vitro and induced tumor growth delay in eight different human cancer xenograft models. PI-103 also demonstrated antiangiogenic potential. Raynaud F.I., et al. "Pharmacologic characterization of a potent inhibitor of class I phosphatidylinositide 3-kinases." Cancer Res. 67: 5840-5850 (2007). PI-103 had antitumor activity in two gefitinib-resistant (please see Cat. No. G-4408, Gefitinib, Free Base) non-small cell lung cancer cell lines, A549 and H460, possibly by simultaneously inhibiting p70s6k phosporylation and Akt phosphorylation due to mTOR inhibition. Zou Z.Q., et al. "A novel dual PI3Kalpha/mTOR inhibitor PI-103 with high antitumor activity in non-small cell lung cancer cells." Int. J. Mol. Med. 24: 97-101 (2009). PI-103 was mainly cytostatic for human leukemic cell lines and induced cell cycle arrest in the G1 phase. In blast cells from AML patients, PI-103 inhibited leukemic proliferation and the clonogenicity of leukemic progenitors, and induced mitochondrial apoptosis. Park S., et al. "PI-103, a dual inhibitor of Class IA phosphatidylinositide 3-kinase and mTOR, has antileukemic activity in AML." Leukemia 22: 1698-1706 (2008). PI-103 inhibited the proliferation of glioma cells, possibly by its ability to inhibit both PI3 kinaseα and mTOR. It showed significant inhibitory activity in xenografted tumors with no observable toxicity. Fan Q.W., et al. "A dual PI3 kinase/mTOR inhibitor reveals emergent efficacy in glioma." Cancer Cell 9: 341-349 (2006). A combined treatment with arsenic disulfide and PI-103 synergistically killed non-acute promyelocytic leukemia cells and promoted their differentiation in vitro. Hong Z., et al. "Arsenic disulfide synergizes with the phosphoinositide 3-kinase inhibitor PI-103 to eradicate acute myeloid leukemia stem cells by inducing differentiation." Carcinogenesis 32: 1550-1558 (2011). PI-103 inhibited endothelial cell proliferation and survival in vitro and tumor growth in vivo possibly by blocking activation of both PI3K and mTOR in vGPCR-expressing endothelial cells. Chaisuparat R., et al. "Dual inhibition of PI3Kα and mTOR as an alternative treatment for Kaposi's sarcoma." Cancer Res. 68: 8361-8368 (2008).

aspirin713 各位好，拜托大家给点建议 我最近在做FCM，主要是测药物对黑色素肿瘤细胞的生长周期的影响，用的方法是FCM PI染色的方法。 但是70%的乙醇固定之后，离心后可以看到有大量的细胞贴壁，把上清吸出去以后，可以看到沉淀留在底部，但是加入了PBS吹打均匀以后再离心。不管怎么样延长时间，或加大转速，就是没有细胞离到壁上，请问大家，这是怎么回事。应该如何避免上面这样的问题出现呢？！ 干细胞之星 固定
